Hi Momoxixi,
Sorry for the late response. So you mean, the invocation of
"table.checkAndPut" may throw a "RetriesExhaustedException" but actually, the
change has been taken effectively in the HBase server side, right?
If so, two comments here:
1) This change adds a "try-catch" embedded in the original "try-catch", the
embedded try-catch should be avoided.
2) Besides the "RetriesExhaustedException", are there other similar cases?
Can it be generalized to "IOException"?
Thanks for your contribution to Kylin!

> KYLIN use hbase to persist resouce metadata. When hbase rpc timeout, kylin
> would rollback the resource timestamp. It caused resource inconsistent
> between kylin's memory and hbase if hbase already put the resource.
